Must sites do not run a vanilla install of WordPress, so in the next section we will look into customizing an image for a site. You have successfully used the base image to run WordPress as a Docker container.
docker run -d -p 80:80 -env-file wp_vars wordpress Run the base image and point the –env-file to the wp_vars file. To use the environment variables file when running the WordPress container we use the –env-file flag. Ensure you set the values to match your environment. Create a new file called wp_vars and then add the following contents. Thankfully, Docker has a feature for setting environment variables via a text file. Now, that isn’t likely something you are going to want to type over and over. docker run -d -p 80:80 -e WORDPRESS_DB_HOST=localhost,WORDPRESS_DB_USER=user1,WORDPRESS_DB_PASSWORD=password,WORDPRESS_DB_NAME=wpsite1 wordpress
The following is an example of running the base WordPress image by setting the database related environment variables. The key variables to know are for configuring the database endpoint.ĭocker provides a flag to set a list of environment variables. The base image accepts a number of environment variables used to configure WordPress. We will use the -p flag to expose the container on port 80 and use the -d flag to daemonize the container to run in the background.įor a typical WordPress install one of the first actions you take will be to configure your database. Let’s run the base image to show the container in action. To pull down a specific version of WordPress add the version tag to the docker pull command. The default action performed by docker pull when no release tag is specified is to pull down the latest image (or :latest>. Notice that no release version was specified in our pull command. Pull the image down into your local repository. It is a bare bones, light weight container running on Alpine Linux. WordPress publishes an official Docker image to Dockerhub. Getting Started Running WordPress Containers In this tutorial you will be progressively guided through each step for running a container in productions, from building the initial image to running it securely and reliabily in production. And while containerizing a WordPress site is not a stren uous activity, building and running a container in production requires a number of considerations. Doing so has many obvious benefits, especially for those developing themes and plugins. Running WordPress sites within a Docker container has grown in popularity since the inception of Docker.
